2013 Mercedes-Benz GL-Classrevealing spy shots

Mercedes-Benz has been spotted once again testing a prototype version of the 2013 Mercedes-Benz GL-Class large SUV. These images show the vehicle in its most revealing guise yet, with very little camouflaging.

As we can see, the upcoming GL-Class will showcase only minor styling tweaks over the current model, while blending hints of the latest Mercedes-Benz design philosophy. There’s still a large front grille filling most of the fascia, incorporating two tiers, however, the headlights will feature a line of LED lights along the top edge.

The front end will still feature a string of LEDs in the corners of the front bumper as well, with the possibility of new spotlights added in. The side mirror casings appear to be less complex in terms of the indicator design, with just one line rather than the current twin layout.

Other exterior revisions for the new model include new taillights and a redesigned tailgate. There’s also a much more curvy, smoother rear bumper design with ’embedded’ taillights in the contours ratherr than a flush layout as seen on the current model. Atop the rear tailgate is a larger spoiler, however, this may be revised for the production vehicles.

Under the bonnet, the 2013 Mercedes-Benz GL-Class will be powered by a range of turbo-diesel and V8 petrol engines, possibly including the new 5.5-litre and 4.7-litre twin-turbo V8 units. Official details are yet to be revealed so we’ll keep you updated.
